Protective sleeve for 33kHz transmitter on 38mm camera head

The protective sleeve is placed over the optionally available 33 kHz transmitter for our large tube cameras with 6.8mm or 9mm pushrod and protects it in the tube from dirt and damage. The sleeve is placed and screwed between the guide ball and the screw ring securing the guide ball. The POM plastic material guarantees that the transmission signal of the 33 kHz frequency is not disturbed or attenuated. The sleeve must always be used together with the insertable transmitter, otherwise the guide ball can no longer be screwed onto the 38mm camera head.
